Very Non-Standard Calling in R

Our group has done a lot of work with non-standard calling conventions in R. Our tools work hard to eliminate non-standard calling (as is the purpose of wrapr::let()), or at least make it cleaner and more controllable (as is done in the wrapr dot pipe). And even so, we still […]

He brilliantly burlesqued a frustrating common occurrence many people say they “have never seen happen.” One of the pains of writing about data science is there […]
